Hydrocortisone | The Pituitary Foundation Treating a pituitary condition Hydrocortisone Hydrocortisone (HC) is a steroid hormone produced by the adrenal gland. It plays a complex role in regulating body functions and is essential for survival. Hydrocortisone is taken as a replacement for the natural hormone where this is deficient, either because there is a failure of hydrocortisone production by the adrenal gland (Addison’s disease/primary adrenal insufficiency), or pituitary deficiency (secondary adrenal insufficiency) of ACTH (the hormone that stimulates the production of hydrocortisone by the adrenal gland). Replacement therapy is also required for people who have congenital adrenal hyperplasia, which is a birth defect. Hydrocortisone is available as tablets under the trade name Hydrocortisone, containing 10mg or 20mg. Prednisolone may be prescribed to individual patients instead of hydrocortisone and works in the same way as hydrocortisone.

Prednisolone is available as tablets under the trade name Deltacortril® containing 2.5mg or 5mg or Prednisolone 1mg or 5mg. Plenadren is a novel, once daily hydrocortisone modified-release tablet, designed to better mimic the body’s natural cortisol production compared to standard treatment. The Plenadren tablet is available in 5 and 20 mg strengths. The immediate release outer coating provides physiological cortisol concentrations within 20 minutes of intake; the extended release core provides a smooth serum cortisol level with reduced exposure in the late afternoon and over the 24-hour period. An injection containing 100mg Hydrocortisone is available for emergency situations for those on hydrocortisone or prednisolone. For children, there are lower dose emergency injections available. How do I take it? The usual dose for hydrocortisone is 15-20mg by mouth, split over two or three times daily, and depending on your individual endocrinologist’s recommendations.

For example: 10mg before getting out of bed in the morning, 5mg at mid-day and 5mg no later than 6pm. Hydrocortisone should ideally be taken with water and is better absorbed if taken before food. The usual dose for prednisolone is 5-7mg by mouth, split over two times daily. When would I need to take more hydrocortisone? If you become ill then the body would naturally increase the output of steroid from your adrenals. Therefore, if you are taking replacement steroid (hydrocortisone) it is essential, to mimic the natural response by increasing your dose appropriately after hydrocortisone or prednisolone. For Plenadren, the dose must be increased temporarily and your doctor may advise you to use other hydrocortisone tablets instead of, or in addition to Plenadren. Please discuss this with your doctor and follow the instructions on how to act in these situations. The daily dose of Plenadren may have to be doubled or tripled in milder conditions such as a mild infection or stress.

You should then take the second dose of Plenadren 6 to 10 hours after the morning dose. If it is not enough to double the daily dose, you should take a third dose 6 to 10 hours after the second dose (6-10 hours intervals between doses). When your illness is over, return to your normal maintenance dose of Plenadren. Please read our Hydrocortisone advice for the pituitary patient for sick day rules and recommendations on increasing your dose. When do I know that I would need an emergency injection? If you cannot absorb your tablets, or your usual replacement wasn’t sufficient for an acute shock or illness, then gradually or perhaps quite quickly, you would feel weak, sickly and light headed. The cortisol clock gives approximate times of need for emergency medical help and replacement. How to give an emergency injection of hydrocortisone Liquid version Efcortesol preparation and administration videos How can I let others know I take replacement hydrocortisone? When you are prescribed your medication you will be given a ‘blue steroid card’ from the hospital to carry.

The Pituitary Foundation suggests that you purchase and wear a medical necklace or bracelet, such as MedicAlert® to show your cortisol replacement therapy. Further, we can provide you with a Pituitary Foundation Patient Care Card which is small enough to fit in your bag, or pocket and displays your hydrocortisone needs and information on emergency replacement should you need this. Emergency injections - should I have these at home? The Pituitary Foundation does recommend all patients taking hydrocortisone (or prednisolone) to have a 100mg injection kit in their home for emergency use only. If you don’t have one of these already, you can ask your GP or endocrinologist if they will prescribe this for you. Please check regularly that these preparations are not expired. You & Your Hormones | Hormones | Cortisol You & Your Hormones Email article to a friend | Last updated: January 19, 2017 Cortisol is a steroid hormone which regulates a wide range of processes throughout the body including metabolism and the immune response. It also has a very important role in helping the body respond to stress. Alternative names for cortisol Hydrocortisone. What is cortisol?

Cortisol is a steroid hormone, known as a glucocorticoid, made in the cortex of the adrenal glands and then released into the blood which transports it all round the body. Almost every cell contains receptors for cortisol and so cortisol can have lots of different actions depending on which sort of cells it is acting upon. These effects include controlling the body’s blood sugar levels and thus regulating metabolism , acting as an anti-inflammatory, influencing memory formation, controlling salt and water balance, influencing blood pressure and helping development of the foetus. In many species cortisol is also responsible for triggering the processes involved in giving birth. A similar version of this hormone, known as corticosterone , is produced by rodents, birds and reptiles. How is cortisol controlled? Blood levels of cortisol vary dramatically, but generally are high in the morning when we wake up, and then fall throughout the day. This is called a diurnal rhythm. In people that work at night, this pattern is reversed, so the timing of cortisol release is clearly linked to daily activity patterns. In addition, in response to stress, extra cortisol is released to help the body to respond appropriately.

The secretion of cortisol is mainly controlled by three inter-communicating regions of the body, the hypothalamus in the brain, the pituitary gland and the adrenal gland. This is called the hypothalamic-pituitary-adrenal axis. When cortisol levels in the blood are low, a group of cells in a region of the brain called the hypothalamus release corticotrophin-releasing hormone which causes the pituitary gland to secrete another hormone, adrenocorticotropic hormone , into the bloodstream. High levels of adrenocorticotropic hormone are detected in the adrenal glands and stimulate the secretion of cortisol, causing blood levels of cortisol to rise. As the cortisol levels rise, they start to block the release of corticotrophin-releasing hormone from the hypothalamus and adrenocorticotropic hormone from the pituitary. As a result the adrenocorticotropic hormone levels start to drop which then leads to a drop in cortisol levels. This is called a negative feedback loop. What happens if I have too much cortisol? Too much cortisol over a prolonged period of time can lead to a condition called Cushing's syndrome .

This can be caused by a wide range of factors such as a tumour that produces adrenocorticotropic hormone (and therefore increases cortisol secretion), or taking certain types of drugs. The symptoms include: Rapid weight gain mainly in the face, chest and abdomen contrasted with slender arms and legs A flushed and round face Skin changes (ie, bruises and purple stretch marks) Mood swings which show as anxiety, depression or irritability Increased thirst and frequency of urination. High cortisol levels over a prolonged time can also cause lack of sex drive and, in women, periods can become irregular, less frequent or stop altogether ( amenorrhoea ). In addition there has been a long-standing association between raised or impaired regulation of cortisol levels and a number of psychiatric conditions such as anxiety and depression. However, the significance of this is not yet clearly understood. What happens if I have too little cortisol? Too little cortisol can be due to a condition called Addison's disease . It has a number of causes, all rare, including damage to the adrenal glands by auto-immune disease. The onset of symptoms is often very gradual. Symptoms may include fatigue, dizziness (especially upon standing), weight loss, muscle weakness, mood changes and the darkening of regions of the skin.

Urgent assessment by a specialist hormone doctor called an endocrinologist is required when a diagnosis of Cushing's syndrome or Addison's disease is suspected. What is cortisol? - Endocrine System - Sharecare What is cortisol? Topics | Endocrine System | What is cortisol? A Answers (4) A American Association of Endocrine Surgeons answered Cortisol, a steroid, has three main functions. It causes the liver to produce sugar and causes break down of muscle and fat to create this sugar. Cortisol also helps the body regulate its response to stress. Lastly, cortisol decreases inflammation and decreases the immune system response. Excess steroids can lead to Cushing’s syndrome, obesity, diabetes, high blood pressure, weak muscles, characteristic bodily changes, and brittle bones. For more information go to endocrinediseases.org: Helpful? 1 person found this helpful. A Dr. Kathleen Hall , Preventive Medicine, answered Cortisol is a stress hormone that has many functions. It is critical for the regulation of our metabolism and the body's use of proteins, carbohydrates, and fats, regulation of blood pressure, and cardiovascular function, and it helps our bodies manage stress.

Cortisol is produced by the adrenal glands in response to signals from the pituitary gland and hypothalamus of the brain. The secretion of cortisol increases in response to psychological or physical stress of any kind. Following a stressful event, adrenaline levels return to normal while cortisol levels can remain elevated over a much longer period of time. Find out more about this book: A Dr. James Lee, MD , Surgery, answered on behalf of Columbia University Department of Surgery Cortisol is a steriod hormone produced by the adrenal gland. The hormone is released in response to stress and low levels of blood sugar and its primary function is to increase blood sugar levels, suppress the immune system and aid in metabolism. A Piedmont Heart Institute answered Cortisol belongs to a class of hormones called glucocorticoids, which affect almost every organ and tissue in the body. The most important job of cortisol is to help the body respond to stress. Among its many vital tasks, cortisol helps: Maintain blood pressure (BP) and cardiovascular function.Slow the immune system's inflammatory response.Maintain levels of glucose-a form of sugar used for energy-in blood.Regulate the metabolism of proteins, carbohydrates, and fats. The amount of cortisol produced by the adrenals is precisely balanced.

Like many other hormones, cortisol is regulated by the brain's hypothalamus and the pituitary gland. First, the hypothalamus releases a "trigger" hormone called corticotropin-releasing hormone (CRH) that signals the pituitary gland. The pituitary responds by sending out adrenocorticotropic hormone (ACTH), which, in turn, stimulates the adrenal glands. The adrenal glands respond by producing cortisol. Completing the cycle, cortisol then signals back to both the pituitary and hypothalamus to decrease these trigger hormones.

How to Prepare for the Test Your doctor will likely have you do the test early in the morning. This is important, because cortisol level varies throughout the day.

You may be asked not to do any vigorous exercising the day before the test. You may also be told to temporarily stop taking medicines that can affect the test, including: Anti-seizure drugs Human-made (synthetic) glucocorticoids, such as hydrocortisone, prednisone and prednisolone Androgens How the Test will Feel When the needle is inserted to draw blood, some people feel moderate pain. Others feel only a prick or stinging. Afterward, there may be some throbbing or slight bruising. This soon goes away. Why the Test is Performed The test is done to check for increased or decreased cortisol production. Cortisol is a glucocorticoid (steroid) hormone released from the adrenal gland in response to adrenocorticotropic hormone (ACTH). ACTH is a hormone released from the pituitary gland in the brain. Cortisol affects many different body systems. It plays a role in: Bone growth Metabolism of fats, carbohydrates, and protein Nervous system function Stress response Different diseases, such as Cushing syndrome and Addison disease , can lead to either too much or too little production of cortisol. Measuring blood cortisol level can help diagnose these conditions.

It is also measured to evaluate how well the pituitary and adrenal glands are working. Other conditions for which the test may be ordered include: Acute adrenal crisis , a life-threatening condition that occurs when there is not enough cortisol Sepsis , an illness in which the body has a severe response to bacteria or other germs Low blood pressure Normal Results Normal values for a blood sample taken at 8 in the morning are 6 to 23 micrograms per deciliter (mcg/dL) or 165.53 to 634.52 nanomoles per liter (nmol/L). Normal value ranges may vary slightly among different laboratories. Some labs use different measurements or may test different specimens. Talk to your doctor about the meaning of your specific test results.

What Abnormal Results Mean A higher than normal level may indicate: Cushing disease , in which the pituitary gland makes too much ACTH because of excess growth of the pituitary gland or a tumor in the pituitary gland Ectopic Cushing syndrome , in which a tumor outside the pituitary or adrenal glands makes too much ACTH Tumor of the adrenal gland that is producing too much cortisol A lower than normal level may indicate: Addison disease, in which the adrenal glands do not produce enough cortisol Hypopituitarism , in which the pituitary gland does not signal the adrenal gland to produce enough cortisol Suppression of normal pituitary or adrenal function by glucocorticoid medicines including pills, skin creams, eyedrops, inhalers, joint injections, chemotherapy Risks Veins and arteries vary in size from one person to another and from one side of the body to the other. Obtaining a blood sample from some people may be more difficult than from others.

Other risks associated with having blood drawn are slight but may include: Excessive bleeding Hematoma (blood accumulating under the skin) Infection (a slight risk any time the skin is broken) Alternative Names Hormones Produced By The Human Body - Testosterone, Human Growth Hormone | Hormones and Anti-Aging Medicine | OptimalHormoneTherapy.com Hormones Are Essential For Healthy Living Discover The Most Important Hormones like Testosterone & HGH for Healthy Aging in both Men & Women Hormones are chemicals that function as your body's messengers to bring important biological information to your cells, tissues and organs.

Hormone levels decline as you age and the receptor cells that receive the imortant biological messages become less efficient at accepting those messages over time. Through Hormone Replacement Therapy or HRT , your physician can help restore normal hormone levels including the primary hormones that can have a real impact on the quality of your life such as Testosterone, Human Growth Hormone, Thyroid, Estrogen, Progesterone, Cortisol, DHEA, Insulin, Melatonin and others. Hormone Optimization entails maintaining healthy hormonal balance at levels that are optimal for your body. When hormone physicians assess your hormone health they will review your bloodwork and determine the level of hormones in your system. Below is a list of some of these important hormones. Testosterone Testosterone, the male sex hormone is a steroid hormone from the androgen group. Testosterone is primarily secreted in the testicles of males and the ovaries of females, although small amounts are also secreted by the adrenal glands in women.

It is the principal male sex hormone and an anabolic steroid. In men, testosterone plays a key role in the development of male reproductive tissues such as the testis and prostate as well as promoting secondary sexual characteristics such as increased muscle, bone mass, deep voice, and the growth of body hair. In addition, testosterone is essential for health and well-being as well as the prevention of osteoporosis (bone loss). Human Growth Hormone Growth hormone (GH or HGH) is a peptide hormone that stimulates growth, cell reproduction and regeneration in humans and other animals. Human Growth hormone is a 191-amino acid, single-chain polypeptide that is synthesized, stored, and secreted by somatotropic cells within the lateral wings of the anterior pituitary gland. Growth hormone or Somatropin for Injection rDNA is used as a prescription drug in medicine to treat children's growth disorders and adult growth hormone deficiency (AGHD). Growth Hormone decline is normally seen in middle-aged adults experiencing menopause or andropausal (male menopaue) symptoms. In the United States, it is only available legally from pharmacies, by prescription from a doctor.

In recent years in the United States, some doctors have started to prescribe growth hormone in HGH-deficient older patients to increase vitality and help reverse the signs and symptoms of aging. The efficacy and safety of this use for HGH has been tested in a variety of medical research and clinical trials. HGH is considered a very complex hormone with many of its functions still waiting to be discovered. In its role as an anabolic agent, HGH has been abused by competitors in sports, bodybuilding and even the Olympics. Estrogen / Estradiol Estrogen is the female sex hormone. The three major naturally occurring estrogens in women are estrone (E1), estradiol (E2), and estriol (E3). Estradiol is the predominant estrogen during reproductive years. During menopause, estrone (E1) is the predominant circulating estrogen and during pregnancy estriol (E3) is the predominant circulating estrogen in terms of serum levels. Though estriol (E3) is the most plentiful of the three estrogens it is also the weakest, whereas estradiol (E2) is the strongest with a potency of approximately 80x that of estriol.

Estradiol is the most important estrogen in non-pregnant females who are before and menopause stage of life. However, during pregnancy this role shifts to estriol, and in postmenopausal women estrone becomes the primary form of estrogen in the body. Another type of estrogen called estetrol (E4) is produced only during pregnancy. All of the different forms of estrogen are synthesized from androgens, specifically testosterone and androstenedione, by the enzyme aromatase. Estradiol is a female sex hormone. Estradiol is abbreviated E2 as it has two hydroxyl groups in its molecular structure. Estrone has one (E1) and estriol has three (E3). Estradiol is about 10 times as potent as estrone and about 80 times as potent as estriol in its estrogenic effect. As discussed above, Estradiol is the predominant estrogen during the reproductive years. During menopause, estrone (E1) is the predominant circulating estrogen and during pregnancy estriol (E3) is the predominant circulating estrogen in terms of serum levels.

Estradiol is also present in males, being produced as an active metabolic product of testosterone. The serum levels of estradiol in males (14 - 55 pg/mL) are roughly comparable to those of postmenopausal women (< 35 pg/mL). Estradiol has not only a critical impact on reproductive and sexual functioning, but also affects other organs, including the bones. Estradiol, like other steroids, is derived from cholesterol. A fraction of androstenedione is converted to testosterone, which in turn undergoes conversion to estradiol by an enzyme called aromatase. In an alternative pathway, androstenedione is aromatized to estrone, which is subsequently converted to estradiol. Progesterone Progesterone also known as P4 is a C-21 steroid hormone involved in the female menstrual cycle, pregnancy (supports gestation) and embryogenesis of humans and other species. Progesterone belongs to a class of hormones called progestogens, and is the major naturally occurring human progestogen.

In women, progesterone levels are relatively low during the preovulatory phase of the menstrual cycle, rise after ovulation, and are elevated during the luteal phase, as shown in diagram below. Progesterone levels tend to be < 2 ng/ml prior to ovulation, and > 5 ng/ml after ovulation. If pregnancy occurs, human chorionic gonadotropin is released maintaining the corpus leuteum allowing it to maintain levels of progesterone. Melatonin Melatonin promotes sleepiness. In humans, melatonin is produced by the pineal gland, a small endocrine gland located in the center of the brain. Circadium Rythm - the melatonin signal forms part of the system that regulates the sleep-wake cycle by chemically causing drowsiness and lowering the body temperature, but it is the central nervous system that controls the daily cycle in most components of the paracrine and endocrine systems. Infants' melatonin levels become regular in about the third month after birth, with the highest levels measured between midnight and 08:00 (8 AM).

In humans, 90% of melatonin is cleared in a single passage through the liver, a small amount is excreted in urine and a small amount is found in saliva. Human melatonin production decreases as a person ages and as children become teenagers, the nightly schedule of melatonin release is delayed, leading to later sleeping and waking times. Production of melatonin by the pineal gland is inhibited by light to the retina and permitted by darkness. Its onset each evening is called the dim-light melatonin onset (DLMO). When used several hours before sleep according to the phase response curve for melatonin in humans, small amounts (0.3 mg[36]) of melatonin shift the circadian clock earlier, thus promoting earlier sleep onset and morning awakening. Besides its function as synchronizer of the biological clock, melatonin also exerts a powerful antioxidant activity. Melatonin is an antioxidant that can easily cross cell membranes and the blood?rain barrier. This antioxidant is a direct scavenger of radical oxygen and nitrogen species. Melatonin works with other antioxidants to improve the overall effectiveness from each antioxidant.

Oxytocin Oxytocin may be considered the Love Hormone and hormone studies have begun to investigate oxytocin's role in various sexual behaviors, including orgasm, social recognition, pair bonding, anxiety, and maternal behavior. There is some evidence that oxytocin promotes bonding and tribal behavior. Hormones have an impact on behavior and Oxytocin seems to foster the trust of accepted group members and rejection of outsiders. This kind of behavior is exhibited in the strong maternal bond a mother has with her own child versus others. The oxytocin receptor gene (OXTR) has also been associated with social traits such as aggression. Insulin Insulin is a peptide hormone produced by the pancreas and is central to regulating carbohydrate, sugar (glucose) and fat metabolism in the body. Insulin helps bring sugar (glucose) into your body's cells to use for energy. The brain also depends on glucose as its primary fuel and red blood cells use only glucose as a fuel. Insulin causes cells in the liver, muscles and fat tissue to take up sugar (glucose) from the blood and store it. In the liver and muscles glucose is converted and stored as glycogen.

In the fatty tissue cells known as adipocytes, it is converted and stored as triglycerides. Insulin is secreted as needed by the pancreas preventing the use of fat as an energy source and inducing the body to properly absorb and convert excess glucose to glycogen and triglycerides. Insulin serves to remove excess sugar (glucose) from the blood which would otherwise become toxic to the body. When blood sugar or glucose levels fall below a certain level, the body is signaled to begin using stored sugar as an energy source through glycogenolysis, which breaks down the glycogen stored in the liver and muscles into glucose, which can then be utilized as an energy source by the body. Glycogenolysis occurs primarily in the liver and is stimulated by the hormones glucagon from the pancreas and epinephrine (adrenaline). When blood glucose levels fall there is an increase in glucagon secretion from the pancreas accompanied by a decrease in insulin secretion so the body uses glucose for energy instead of storing it. When blood glucose levels rise, insulin is released to help the cells absorb sugar and to store any excess sugar as glycogen and triglycerides thereby maintaning proper glucose levels in the body.

Gluconeogenesis helps to maintain the glucose level in the blood so that the brain and muscles can extract sufficient glucose from it to meet their metabolic demands. Insulin also signals amino acid uptake by body cells and has other anabolic effects throughout the body. When you've been sick or injured, or if you're recovering from surgery, insulin helps you heal by bringing amino acids which are the building blocks of muscle protein to your injured muscles. Amino acids help repair muscular damage and help them regain their size and strength. If there isn't enough insulin in your body when your muscles have been injured or when you are sick, amino acids can't do their job. In the absence of insulin or in conditions where insulin is too low, glucose is not taken up by body cells and the body begins to use fat as its source of energy. If your body is unable to secrete suffcient insulin as needed, overnight your liver will release too much glycogen into your blood stream creating a toxic condition. People with diabetes have too high a blood glucose level, also called high blood sugar or hyperglycemia. Diabetes is a disorder of the metabolism or the way the body uses digested food for energy.

When insulin is no longer is secreted (Diabetes1) or secreted in too low a level (Diabetes 2), blood sugar levels will be too high. In addition a person's body may no longer effectively use insulin and a glucose build will result. Insulin therapy is used to treat diabetes by replenishing insulin the body needs to properly absorb and synthesize glucose (Blood Sugar). Patients with type 1 diabetes depend on external insulin which is usually injected subcutaneously for their survival because the hormone is no longer produced internally. Patients with type 2 diabetes are insulin resistant and suffer from an insulin deficiency. Thyroid The thyroid gland is one of the largest endocrine glands in the human body. The thyroid gland is found in the neck below the thyroid cartilage or Adam's apple. The thyroid gland controls how quickly the body uses energy, makes proteins and how sensitive the body is to other hormones. The thyroid gland participates in these biological processes by producing thyroid hormones, the main ones being triiodothyronine (T3) and (T4) thyroxine - also referred to as tetraiodothyronine. T3 & T4 thyroid hormones regulate the rate of metabolism and affect the function of many other systems in the body.

T3 and T4 are synthesized from both iodine and tyrosine. The thyroid also produces calcitonin, which plays a role in calcium homeostasis. Hormonal output from the thyroid is regulated by thyroid-stimulating hormone (TSH) produced by the anterior pituitary, which itself is regulated by thyrotropin-releasing hormone (TRH) produced by the hypothalamus. The most common hormonal imbalance problems of the thyroid gland consist of an overactive thyroid gland, referred to as hyperthyroidism, and an underactive thyroid gland, referred to as hypothyroidism. Hypothyroidism is treated with hormone replacement therapy (HRT) using a hormone medication such as levothyroxine which is typically required to be taken for the rest of the patient's life. Thyroid hormone treatment is given under the care of a licensed physician and can take a few weeks to become effective in order to alleviate symptoms. Cortisol Cortisol, also known as hydrocortisone, is a steroid hormone or glucocorticoid produced by the adrenal glands. It is released in response to stress.

Its primary functions of cortisol are to increase blood sugar through gluconeogenesis which is the release of glycogen (stored sugar) from the liver and muscle. Cortisol also suppresses the immune system, and aids in fat, protein and carbohydrate metabolism. Cortisol hormone prevents the release of substances in the body that cause inflammation. Cortisol stimulates gastric-acid secretion and inhibits loss of sodium from he body. Too much cortisol can weaken the activity of the immune system, counteract insulin, inhibit collagen and bone formation. Hydrocortisone is used to treat endocrine, gland and hormone disorders, arthritis, lupus, skin disease, allergies, autoimmune disorders, swelling, asthma or other breathing problems. Prolactin Prolactin is a peptide hormone made by the pituitary gland. Pregnant women have high levels of prolactin which helps to make breast milk. During pregnancy, prolactin levels increase and after the baby is born prolactin stays high if a mother is breast-feeding. In women who do not breast-feed, prolactin levels return to normal soon after they give birth.

After months of breast-feeding, prolactin levels may also return to normal levels even if a woman is still breast-feeding. The pituitary gland in men and non-pregnant women also produce prolactin but at a much lower level. Prolactin hormone levels are different throughout the day with the highest levels occur during sleep and shortly after you wake up which is very similar to Human Growth Hormone. Prolactin levels also get higher during times of physical or emotional stress as do cortisol levels. Leptin Leptin is a protein hormone that plays a key role in regulating energy intake and energy expenditure including appetite, hunger and metabolism. It is one of the most important adipose or fatty tissue-derived hormones. Leptin inhibits appetite and signals the body that it has had enough to eat. The level of circulating leptin is proportional to the total amount of fat in the body. The absence of leptin or its receptor cells can lead to uncontrolled food intake resulting obesity. Fasting or following a very-low-calorie diet lowers leptin levels which signals hunger to the brain. Leptin is more sensitive to starvation than to overfeeding and leptin levels change more when less food is eaten than when more is eaten.

DHEA DHEA is known as Dehydroepiandrosterone, as androstenolone or prasterone, and is a very important steroid hormone. DHEA is known for being the most abundant circulating steroid hormone in human beings. DHEA hormoe is produced in the adrenal glands, in the gonads and in the brain where it functions to assist with metabolism and synthesis of androgen and estrogen sex hormones. DHEA reaches its peak levels in the morning and regular exercise and a restricted diet help increase DHEA in the body. Naturally, DHEA is produced from cholesterol and converted to the hormone pregnenolon by enzymes and then to DHEA. For hormone supplementation, DHEA hormone supplements may be produced from wild yam or soy. Taking too much of a DHEA supplement could cause irritability and aggressiveness so as with all anti-aging supplements careful dosing is important. Although DHEA is predominantly a precursor to more potent androgens such as testosterone and estrogen, DHEA has some direct androgenic effect as well. Precursors are the substances that are converted by the body into hormones.

Like Testosterone and HGH, DHEA production peaks in persons mid-20s and production gradually declines with age along with Testosterone, HGH, progesterone and estrogen production. DHEA supplements can help increase the level of these hormones and provide some healt benefits like boosting adrenal gland, strengthening the immune and nervous system, slow some efects of aging, increasing energy, improving mood, focus and memory, and building muscle strength. Most people take DHEA supplements for Anti-Aging purposes and it is not permitted for body-building or professional sports including Olympic athletes. Since DHEA levels decline with age along with HGH and Testosterone, hormone replacement therapy may inlcude DHEA. Some small clinical studies have reported positive anti-aging effects from the use of DHEA supplements. HCG Human chorionic gonadotropin (HCG) is a hormone produced during pregnancy that is made by the developing placenta after conception. Human chorionic gonadotropin or HCG is as an ovulation inducer in place of LH or luteinizing hormone.

When mature ovarian follicles exist, ovulation can be triggered by the administration of HCG injections and ovulation will happen between 38 and 40 hours after the HCG injection. HCG is also used by some weight loss doctors and hormone therapy doctors to help patients manage weight and counteract the effects of testosterone replacment therapy. FSH Follicle-stimulating hormone (FSH) is a hormone synthesized and secreted by gonadotrophs of of the pituitary gland. FSH is responsible for regulating development, growth, puberty and reproductive functions of the body. FSH and luteinizing hormone (LH) act together in reproduction. An increase in FSH secretion causes ovulation in women. Menopuase is the most common reason for too high a serum of FSH concentration in women as the gonads no longer provide the feedback loop to shut down FSH secretion. In men, too low an FSH level signifies the shutting down of the gonads (hypogonadism) during Andropause (the male menopause) and adversely affects the production and quality of sperm.

Hypogonadism is chracterized by a decline in the free testosterone available to men for use by their bodies. LH Luteinizing hormone (LH), is also known as lutropin or lutrophin and is a hormone produced by gonadotroph cells in the pituitary gland. In females an increase in LH triggers ovulation and the development of the corpus luteum. In males LH serves as an interstitial cell-stimulating hormone stimulating the testes' Leydig cells to produce testosterone. LH works together with FSH in both men and women.

 know the feeling whether it’s your hands trembling as you flip through a blank exam or trouble sleeping while you worry about approaching deadlines.

Stress is an inevitable aspect of life through college and beyond. While everyone understands the symptoms of the stress response, few know the underlying physiological mechanisms. When we probe beneath the surface of our anxiety, an elegant balance of stimuli and responses emerges. This paper will present a broad discussion of stress: how stress is defined, the chemistry and physiology underlying it at the cellular level, and the micro and macro level consequences of the stress response. Defining Stress Understanding the biochemical interactions that constitute the stress response requires a definition of stress. In the realm of biology, stress refers to what happens when an organism fails to respond appropriately to threats (1). While the “threats” humans face today often take more benign forms compared to those our hunter-gatherer ancestors faced, they can be equally taxing on our bodies. Some stress, of course, can be beneficial. The pressure it exerts can be an incentive to accomplish necessary goals. Often, however, stress reaches chronic, harmful levels, and deleterious consequences follow, from compromised immune function to weight gain to developmental impairment (2). The intensity of the stress response is governed largely by glucocorticoids, the primary molecules involved in the stress response.

Stress can be ephemeral and beneficial, or it can be long-lasting and harmful, causing suffocation, depression, and paralysis (3). Proper stress management takes on great importance given the wide range of bodily systems impacted by stress hormones. Neurochemistry of Stress Schematic diagram of how stress affects the body. The human stress response involves a complex signaling pathway among neurons and somatic cells. While our understanding of the chemical interactions underlying the stress response has increased vastly in recent years, much remains poorly understood. The roles of two peptide hormones, corticotropin-releasing hormone (CRH) and arginine-vassopressin (AVP), have been widely studied. Stimulated by an environmental stressor, neurons in the hypothalamus secrete CRH and AVP. CRH, a short polypeptide, is transported to the anterior pituitary, where it stimulates the secretion of corticotropin (4). Consequently, corticotropin stimulates increased production of corticosteroids including cortisol, the primary actor directly impacting the stress response (5).

Vasopressin, a small hormone molecule, increases reabsorption of water by the kidneys and induces vasoconstriction, the contraction of blood vessels, thereby raising blood pressure (6). Together, CRH and vasopressin activate the hypothalamic-pituitary-adrenal (HPA) axis. The HPA axis comprises the system of feedback interactions among the hypothalamus, pituitary gland, and adrenal glands (7). In sum, the hypothalamus releases CRH and vasopressin, which activate the HPA axis. CRH stimulates the anterior pituitary to release corticotropin, which travels through the bloodstream to the adrenal cortex, where corticoptropin then upregulates cortisol production. Vasopressin, the other hormone secreted by the hypothalamus, stimulates the cortical collecting ducts of the kidneys to increase reuptake of water, resulting in smaller volumes of urine formed. As the next section will illuminate, corticosteroids such as cortisol act across the entire body to promulgate the stress response (8).

Cortisol: Stress Hormone Cortisol is a glucocorticoid hormone synthesized from cholesterol by enzymes of the cytochrome P450 family in the zona fasciculata, the middle area of the adrenal cortex (9). Regulated via the HPA axis, cortisol is the primary hormone responsible for the stress response. Expressed at the highest levels in the early morning, cortisol’s main function is to restore homeostasis following exposure to stress (10). The effects of cortisol are felt over virtually the entire body and impact several homeostatic mechanisms. While cortisol’s primary targets are metabolic, it also affects ion transport, the immune response, and even memory. Cortisol counters insulin by encouraging higher blood sugar and stimulating gluconeogenesis, the metabolic pathway that synthesizes glucose from oxaloacetate. The presence of cortisol triggers the expression of enzymes critical for gluconeogenesis, facilitating this increase in glucose production. Conversely, it also stimulates glycogen synthesis in the liver, which decreases net blood sugar levels (11). In these ways, cortisol carefully regulates the level of glucose circulating through the bloodstream.

Cortisol’s beneficial effects are clear from its role in metabolism: during states of fasting, when blood glucose has been depleted, cortisol ensures a steady supply of glucose via gluconeogenesis. Cortisol’s role in ion regulation, particularly regarding sodium and potassium, has also been widely studied. Cortisol prevents cells from losing sodium and accelerates the rate of potassium excretion. This helps regulates bodily pH, bringing it back into equilibrium after a destabilizing event. Cortisol’s ability to regulate the action of cellular sodium-potassium pumps has even led to speculation that it originally evolved as a sodium transporter (12). Structure of cortisol. Cortisol’s weakening effects on the immune response have also been well documented. T-lymphocyte cells are an essential component of cell-mediated immunity. T-cells respond to cytokine molecules called interleukins via a signaling pathway. Cortisol blocks T-cells from proliferating by preventing some T-cells from recognizing interleukin signals. It also stifles inflammation due to inhibition of histamine secretion (13). Cortisol’s ability to prevent the promulgation of the immune response can render individuals suffering from chronic stress highly vulnerable to infection. A role for cortisol in memory has also been demonstrated.

The hippocampus, the region of the brain where memories are processed and stored, contains many cortisol receptors. While normal cortisol levels have no adverse effects on the hippocampus, excess cortisol overwhelms the hippocampus and actually causes atrophy. Studies of the elderly have indicated that those with elevated cortisol levels display significant memory loss resulting from hippocampus damage, but the exact age range at risk is unclear. There is a reprieve, however, for the chronically stressed: the damage incurred is usually reversible (14). Finally, cortisol participates in an inhibitory feedback loop by blocking the secretion of corticotripin-releasing hormone, preventing the HPA axis interactions central to glucocorticoid secretion. Many in the scientific community speculate that chronic levels of high stress disrupt the delicate feedback balance, resulting in the failure of feedback inhibition to operate and the continued release of cortisol (15). Sleep Deprivation, Caffeine, and Alcohol All Increase Cortisol Stressed Dartmouth students often sacrifice sleep while increasing consumption of caffeine and alcohol, all of which impact cortisol levels and thus, the physiological markers of the stress response.

While no connection has yet been established linking sleep deprivation to long-term HPA axis activity, acute sleep loss confuses the HPA axis and disrupts negative glucocorticoid feedback regulation (16). Leproult et al. found that plasma cortisol levels were elevated by up to 45 percent after sleep deprivation, an increase that has implications including immune compromise, cognitive impairment, and metabolic disruption (17). These consequences should give pause to anyone contemplating an all-nighter the day before an exam. The relationships among caffeine, stress, and cortisol secretion will also be of interest to Dartmouth’s caffeinated masses. Repeated doses of caffeine over a single day result in markedly increased cortisol levels, regardless of the stressor involved or the sex of the individual. Although the extent of the link has not been fully elucidated, a positive relationship clearly exists between caffeine intake and cortisol release, and this relationship is exacerbated when other stressors are introduced. Thus, supplementing a lack of sleep with multiple cups of coffee or energy drinks actually reinforces the negative effects of the stress response and further undermines performance. The benefits of caffeine intake must be balanced with its implications for cortisol secretion.

(18) Often, students decide to celebrate after a stressful episode by consuming alcohol, often in large quantities over a short time frame. Ironically, this method of releasing stress actually stimulates the HPA axis and encourages the manufacture and release of cortisol. In fact, the elevation in glucocortioid levels as a result of alcohol consumption can be greater than the elevation from stressful stimuli. Alcohol probably functions to activate the HPA axis by disinhibiting it: alcohol depresses the nerve cells responsible for HPA inhibition, thereby elevating HPA axis activity (19). As a result, the adrenal cortex secretes higher levels of cortisol. It is hardly surprising, then, that Dartmouth students and college students generally complain of the consequences of considerable anxiety and pressure: our common responses to stress, lack of sleep, caffeine intake, and alcohol consumption act in conjunction to raise the amount of cortisol in our bodies, augmenting the very stress we seek to combat. Stress and Health: Short-Term and Long-Term Effects Many of us know from experience that stress compromises the immune response, an empirical observation buttressed by our understanding of cortisol’s physiological effects. Indeed, the effects of acute and chronic stress on human health are myriad and severe.

During periods of increased stress, “the immune cells are being bathed in molecules which are essentially telling them to stop fighting,” according to Dr. Esther Sternberg (20). These molecules, namely cortisol, suppress the immune system and inflammatory pathways, rendering the body more susceptible to disease. High levels of stress, even over relatively short periods and in vastly different contexts, tend to produce similar results: prolonged healing times, reduction in ability to cope with vaccinations, and heightened vulnerability to viral infection (21). The long-term, constant cortisol exposure associated with chronic stress produces further symptoms, including impaired cognition, decreased thyroid function, and accumulation of abdominal fat, which itself has implications for cardiovascular health. The bottom line is that both episodes of acute stress and more prolonged stressful circumstances precipitate lower levels of general health, and exposure to such stress should be minimized. In the most extreme cases, Cushing’s Syndrome, characterized by dangerously high cortisol levels, can result. Those afflicted with Cushing’s experience rapid weight gain, hyperhydrosis, and hypercalcemia, along with various psychological and endocrine problems (22). Conclusion Stress is unavoidable. Our bodies are designed to react to our environment in an effort to preserve homeostasis.

Arming ourselves with an understanding of the mechanisms, agonists, and antagonists of the stress response, however, positions us to minimize stress and its impact on our minds and bodies. It is both a blessing and a curse that the HPA axis evolved to be so sensitive to factors like circadian rhythm, caffeine, and alcohol. We are experts at maintaining homeostasis but often novices at managing stressful circumstances. The good news is that stress levels rest largely on our own behavior and decisions and that we can optimize our bodies’ responses to stress based on how we live our daily lives. hydrocortisone CONTACT About Hydrocortisone/Cortisol Hydrocortisone and Cortisol refer to the same compound. Cortisol, known more formally as Hydrocortisone is produced in the human body by the adrenal gland in the zona fasciculata, the second of three layers comprising the adrenal cortex. The cortex forms the outer sheath of each adrenal gland, situated atop the kidneys, as per the diagram to the left. Hydrocortisone is not to be confused with Cortisone, a similar compound with a similar name, genesis, and function.

Sufficient hydrocortisone is essential for a balanced immune system. On one hand it is required for a efficiently functioning immune system in times of infection, stress and detoxification, and on the other hand it is required to limit the degree of inflammation in the system. It is a hormone produced in response to stress. Hydrocortisone also plays an important role in the regulation of carbohydrates, fats and proteins. Hydrocortisone fights inflammation, helps regulate blood pressure and helps stabilize cardiovascular function. Hydrocortisone regulates the body's fight or flight mechanism, the body's normal release of adrenaline by the adrenal glands. Low hydrocortisone levels cause varying symptoms amongst different individuals. The main indicator of chronic low hydro-cortisone levels is fatigue and low blood pressure. Adrenal insufficiency/fatigue is a major factor in poor health for many people, possibly as high as 50% of the population of industrialized countries. For these people, the first step in restoring health must be to support adrenal hormone output. It is the hormone hydro-cortisone that is inescapably essential for improving health.

So, for these people supplementing with bio-identical hydro-cortisone is the gateway to the journey into wellness. Why such widespread deficiency? This situation has arisen due to either; acquired adrenal insufficiency from birth or childhood, or most commonly from the many years of demands of hyper-civilization; stress, modern lifestyle, poor nutrition and not enough rest to recover. Further, EMF exposure, in this age of electronic devices (computers, TVs, mobile devices and so on), impacts upon the adrenal glands. Eventually many people end up shifting from this hyper-civilization mode to a burn-out phase of constant tiredness and insufficient energy to do what we used to do. The result is adrenal insufficiency/fatigue. This means that the adrenal glands are unable to produce sufficient hydro-cortisone to maintain health and adapt to life’s challenges, be they physical, mental, emotional or physiological.

See also adrenal glands , hormones; Table 1. Table 1: Hormones Cortisol and How It Affects Adrenal Health | Adrenal Fatigue Heart and blood vessel tone and contraction Central nervous system activation Cortisol levels normally fluctuate throughout the day and night in a circadian rhythm that peaks at about 8 AM and reaches it lowest around 4 AM. While it is vital to health for the adrenals to secret more cortisol in response to stress, it is also very important that bodily functions and cortisol levels return to normal following a stressful event.

Unfortunately, in our current high-stress culture, the stress response is activated so often that the body does not always have a chance to return to normal.* This can lead to health problems resulting from too much circulating cortisol and/or from too little cortisol if the adrenal glands become chronically fatigued (adrenal fatigue). Higher and more prolonged levels of circulating cortisol (like those associated with chronic stress) have been shown to have negative effects, such as:* Impaired cognitive performance Blood sugar imbalances, such as hyperglycemia Decreased bone density Adrenal Glands | Johns Hopkins Medicine Health Library Adrenal Glands: What You Need to Know Adrenal glands, also known as suprarenal glands, are small, triangular-shaped glands located on top of both kidneys. Adrenal glands produce hormones that help regulate your metabolism, immune system, blood pressure, response to stress and other essential functions. Adrenal glands are composed of two parts — the cortex and the medulla — which are each responsible for producing different hormones. When adrenal glands don’t produce enough hormones, this can lead to adrenal insufficiency (Addison’s disease). Adrenal glands may develop nodules that can be benign or malignant.

These nodules may produce excessive amounts of certain hormones leading to various health issues. Anatomy of the Adrenal Glands An adrenal gland is made of two main parts: The adrenal cortex is the outer region and also the largest part of an adrenal gland. It is divided into three separate zones: zona glomerulosa, zona fasciculata and zona reticularis. Each zone is responsible for producing specific hormones. The adrenal medulla is located inside the adrenal cortex in the center of an adrenal gland. It produces several “stress hormones,” including adrenaline. The adrenal cortex and adrenal medulla are enveloped in an adipose capsule that forms a protective layer around an adrenal gland. Hormones of the Adrenal Glands The role of the adrenal glands in your body is to release certain hormones directly into the bloodstream. Many of these hormones have to do with how the body responds to stress, and some are vital to existence. Both parts of the adrenal glands — the adrenal cortex and the adrenal medulla — perform distinct and separate functions. Each zone of the adrenal cortex secretes a specific hormone.

The key hormones produced by the adrenal cortex include: Cortisol Cortisol is a glucocorticoid hormone produced by the zona fasciculata that plays several important roles in the body. It helps control the body’s use of fats, proteins and carbohydrates; suppresses inflammation; regulates blood pressure; increases blood sugar; and can also decrease bone formation. This hormone also controls the sleep/wake cycle. It is released during times of stress to help your body get an energy boost and better handle an emergency situation. How Adrenal Glands Work to Produce Cortisol Adrenal glands produce hormones in response to signals from the hypothalamus and the pituitary gland in the brain. For example, for the adrenal gland to produce cortisol: The hypothalamus produces corticotropin-releasing hormone (CRH) that stimulates the pituitary gland to secrete adrenocorticotropin hormone (ACTH). The ACTH then stimulates the adrenal glands to make and release cortisol hormones into the blood. Normally, both the hypothalamus and the pituitary gland can sense whether the blood has the right amount of cortisol in it.

If there is too much or too little cortisol, these glands respectively change the amount of CRH and ACTH that gets released. Excess cortisol production can occur from nodules in the adrenal gland or excess production of ACTH from a tumor in the pituitary gland or other source. Aldosterone This mineralocorticoid hormone produced by the zona glomerulosa plays a central role in regulating blood pressure and certain electrolytes (sodium and potassium). Aldosterone sends signals to the kidneys, resulting in the kidneys absorbing more sodium into the bloodstream and releasing potassium into the urine. This means that aldosterone also helps regulate the blood pH by controlling the levels of electrolytes in the blood. DHEA and Androgenic Steroids These hormones produced by the zona reticularis are weak male hormones. They are precursor hormones that are converted in the ovaries into female hormones (estrogens) and in the testes into male hormones (androgens). However, estrogens and androgens are produced in much larger amounts by the ovaries and testes.

Epinephrine (Adrenaline) and Norepinephrine (Noradrenaline) The adrenal medulla, the inner part of an adrenal gland, controls hormones that help you cope with physical and emotional stress. The main hormones secreted by the adrenal medulla include epinephrine (adrenaline) and norepinephrine (noradrenaline), which have similar functions. Among other things, these hormones are capable of increasing the heart rate and force of heart contractions, increasing blood flow to the muscles and brain, relaxing smooth muscles, and assisting in sugar metabolism. They also control the squeezing of the blood vessels (vasoconstriction), helping maintain blood pressure and increasing it in response to stress. Like several other hormones produced by the adrenal glands, epinephrine and norepinephrine are often activated in stressful situations when your body needs additional resources and energy to endure unusual strain. Adrenal Gland Disorders The two common ways in which adrenal glands cause health issues are by producing too little or too much of certain hormones, which leads to hormonal imbalances. These abnormalities of the adrenal function can be caused by various diseases of the adrenal glands or the pituitary gland.

Adrenal Insufficiency Adrenal insufficiency is a rare disorder. It may be caused by disease of the adrenal glands (primary adrenal insufficiency, Addison’s disease) or by diseases in the hypothalamus or the pituitary (secondary adrenal insufficiency). It is the opposite of Cushing syndrome and is characterized by low levels of cortisol (and aldosterone in the primary form). The symptoms include weight loss, poor appetite, nausea and vomiting, fatigue, darkening of skin (only in primary adrenal insufficiency), abdominal pain, etc. The causes of primary adrenal insufficiency may include autoimmune disorders, fungal and other infections, cancer (rarely), and genetic factors. Although adrenal insufficiency usually develops over time, it can also appear suddenly as an acute adrenal failure (adrenal crisis). It has similar symptoms, but the consequences are more serious, including coma, shock and seizures. These may develop if the condition is left untreated. Congenital Adrenal Hyperplasia Adrenal insufficiency can also result from a genetic disorder called congenital adrenal hyperplasia. Children who are born with this disorder are missing an essential enzyme necessary to produce cortisol, aldosterone or both.

At the same time, they often experience excess of androgen, which may lead to male characteristics in girls and precocious puberty in boys. Congenital adrenal hyperplasia can remain undiagnosed for years depending on the severity of the enzyme deficiency. In more severe cases, infants may suffer from dehydration, vomiting and failure to thrive. Overactive Adrenal Glands Sometimes, adrenal glands may develop nodules that produce too much of certain hormones. Nodules 4 centimeters or larger and nodules that show certain features on imaging may be cancerous. Both benign and cancerous nodules may produce excessive amounts of certain hormones, which often is referred to as an overactive adrenal gland . Excess of Cortisol: Cushing Syndrome Cushing syndrome results from excessive production of cortisol from the adrenal glands. The symptoms may include weight gain and fatty deposits in certain areas of the body, such as the face, below the back of the neck and in the abdomen; thinning arms and legs; purple stretch marks on the abdomen; facial hair; fatigue; muscle weakness; easily bruised skin; high blood pressure; diabetes; and other health issues.

Excess cortisol production can also be triggered by overproduction of ACTH by a benign tumor in the pituitary gland. This is known as Cushing Disease. Another common cause of Cushing syndrome is excessive and prolonged consumption of external steroids, such as prednisone or dexamethasone, which are prescribed to treat many autoimmune or inflammatory diseases (e.g., lupus, rheumatoid arthritis, asthma, inflammatory bowel disease, multiple sclerosis, etc.) Excess of Aldosterone: Hyperaldosteronism Hyperaldosteronism results from overproduction of aldosterone from one or both adrenal glands. This is characterized by increase in blood pressure that often requires many medications to control. Some people can develop low potassium levels in the blood, which can cause muscle aches, weakness and spasms. When the cause is a benign tumor in one adrenal gland, the disease is called Conn syndrome. Excess of Adrenaline or Noradrenaline: Pheochromocytoma Pheochromocytoma is a tumor that results in excess production of adrenaline or noradrenaline by the adrenal medulla that often happens in bursts.

Occasionally, neural crest tissue, which is similar to the adrenal medulla, may be the cause of overproduction of these hormones. This condition is called a paraganglioma. Pheochromocytomas may cause persistent or sporadic high blood pressure that may be difficult to control with regular medications. Other symptoms include headaches, sweating, tremors, anxiety and rapid heartbeat. Some people are genetically predisposed to developing this type of tumor. Adrenal Cancer Malignant adrenal tumors (adrenal cancer), such as adrenocortical carcinoma, are rare and often have spread to other organs and tissues by the time they are diagnosed. These tumors tend to grow fairly large and can reach several inches in diameter. Adrenal cancer may cause adrenal glands to produce excess of one or more hormones accompanied by corresponding symptoms, as listed above. You may also experience abdominal pain or flank pain and a feeling of fullness if the adrenal tumor gets very large. Not all cancers found in adrenal glands start there. Most adrenal cancers are secondary cancers that start elsewhere in the body and spread to the adrenal glands. Experience Our Care
